Impact of 3 km walk in groups

By walking 3 km daily how much weight will be reduced.
Example:
Age: 30
Weight: 70 kg
Sex: Female
Time Duration: 45 minutes
Period: 7 days (1 week)
Walk Type: Brisk walking (5 km/h)
Calculations:
Calories Burned: Brisk walking at 5 km/h burns approximately 314 calories per hour for a person weighing 70 kg.
Total Calories Burned: 314 calories/hour * 0.75 hours (45 minutes) = 235.5 calories per day
Weekly Calorie Deficit: 235.5 calories/day * 7 days = 1,648.5 calories
Weight Loss: One pound of body weight is roughly equal to 3,500 calories.
Assuming a pound of weight loss requires a calorie deficit of 3,500 calories, the potential weight loss for the week would be:
Weight Loss: 1,648.5 calories / 3,500 calories = 0.47 pounds (approximately 0.2 kg)

How much weight will you lose while walking 2 Km a day for 60 days?

Weight Loss:
One pound of body weight is roughly equal to 3,500 calories.
Assuming a pound of weight loss requires a calorie deficit of 3,500 calories, the potential weight loss for the week would be:
Weight Loss: 1,099 calories / 3,500 calories = 0.31 pounds (approximately 0.14 kg)
By walking 2 km daily for 30 minutes at a brisk pace, a person weighing 70 kg could potentially lose around 0.14 kg in one week.
